ubuntu root password

ubuntu root account

This is the mystery for most users - you didn't set a root password,
so what is it? The root user (also known as superuser), is a user on
Ubuntu Linux and Unix-like systems with full administrative privileges
(full access). So using root account for daily work can be very
dangerous and you may damage your working system.

Ubuntu and root account

By
default root account is locked under Ubuntu Linux. Therefore, you
cannot login as root or use 'su -' command to become a superuser. To run
all administrative command use sudo command. sudo allows a permitted
user to execute a command as the superuser or another user. Ubuntu setup
your default account (the one created during installation) to run all
administrative commands.
For example create a new user called bar, you need to type sudo command as follows:$ sudo adduser bar Password:
When sudo asks for a password, you need to supply YOUR OWN password. In other words a root password is not needed. Here are few more examples.

Task: Avoid typing sudo each and every time

Note that this is not recommended until and unless you are an expert and aware of what you are typing:$ sudo -i
Above command will start /bin/bash as a root shell so that you can enter a root user command without using sudo command.

How do I login as root user?

Open terminal and simply type the following command:$ sudo bash OR$ sudo -s Supply your password and you will become a root user.
